In United States v. Rahimi, the Supreme Court denied that the Second Amendment is “a law trapped in amber.” The amber metaphor, we might say, had itself become frozen in amber. Before Rahimi, lower court decisions on whether the law was “trapped” or “frozen” in “amber” numbered in the dozens. By my count, the amber metaphor recently appeared in six different Supreme Court cases, including two majority opinions. If the law is not trapped in amber, the Supreme Court seems to be.
